Thanks to modern technical equipment, the work of the painter has become more flexible. This fact lies not only in the availability of new equipment, but also in its varieties. Today, LVLP pneumatic spray guns are popular.
What it is?
These spray guns are primarily devices for the smooth application of colorants to various surfaces. Mostly LVLP is used when working with different parts of cars or any tools, buildings. The naming system is designed in such a way that it allows you to demonstrate the most important qualities of technology.
In this case, LVLP stands for Low Volume Low Pressure, which means low volume and low pressure. Due to these characteristics, this type of spray gun is versatile, and can be used by both experienced workers and beginners.
How is it different from HVLP?
HV stands for High Volume, that is, high volume. This type of spray gun requires a suitable compressor to handle the required performance. Created in the 80s of the last century, HVLPs were presented in the form of a tool capable of causing minimal harm to the environment.
In this regard, these units are distinguished by a low speed of paint release, so they should be used at a distance of no more than 15 cm from the workpiece. A complete set in the form of a powerful compressor requires the installation of additional filters to clean the air from moisture and oil, in contrast to electrical and other types of similar devices.
LVLP, in turn, is a late model in time of creation, capable of applying colorants in the same ratio of volume and pressure, which makes the workflow smoother and without the presence of smudges, which is inherent in HVLP.
Differences in the form of lower air consumption, low cost and the ability to work with materials at a greater distance make this type of spray gun more preferable for private and spot use, where operation is not constant and does not require special speed and volume of execution.
Device and principle of operation
The device of spray guns LVLP, like other pneumatic models, is quite simple. In this case, the paint reservoir is located on top and is made of a translucent material, so that the worker can observe the amount of the coloring substance . A hose is connected to the gun to the compressor. It, in turn, compresses the required amount of air, and after you pull the trigger, the mechanism will spray the substance.
The trigger has two positions, which makes it possible to adjust the amount of paint dispensed . The first full thrust position will use the maximum possible pressure, in which case the closing needle will not be pulled back. The second position requires you to press about halfway down, so you can adjust the material flow based on the force exerted.
In this case, the head will be less, and so that most of the paint is not wasted, you need to get closer to the surface to be treated. Due to their small volume, pressure and their simplicity, LVLP units are among the most convenient for domestic use . The principle of operation is easy to learn, since the low power of the compressor and the ability to install different types of handpieces do not require special skills.
Selection Tips
In order to choose the right spray gun, you must adhere to certain criteria. First of all, they relate to the scope of the technology. LVLP models, for example, perform best when they are neat and spotty when painting small or unusual parts. Due to the small volume and pressure, the user can adjust the amount of sprayed paint by means of the trigger.
Having decided on a specific type of device, you should pay attention to individual characteristics . The pressure level will tell you how effectively the paint can be used and how evenly you can apply it. Of course, in this case, the effectiveness of the coating also plays a significant role, which is calculated as a percentage. The higher the pressure, the higher the ratio and, accordingly, less paint will simply be dispersed into the environment.
This characteristic is also important when choosing a compressor, since it must be calculated as necessary, based on the characteristics of the selected spray gun.
The next important quality is versatility. It consists in the ability of the tool to apply material to a wide variety of surfaces, while not losing quality . This feature depends not so much on the technical equipment of the unit as on its configuration in the form of nozzles and various nozzle diameters.
It is very important to select based on the volume of the tank . The higher it is, the heavier the unit will be in the end, but the more you can paint in one run. If the volume is small, this will increase ease of use, but frequent replenishment of the dye will be required. Again, if you are using a small part for painting, then a smaller capacity is more suitable.
Do not forget about the technical equipment of the model, which is the possibility of adjustment . As a rule, it is expressed in the form of a dial or knob so that the worker can change the output of the equipment. The more varied the adjustment, the better, since in some situations the best solution would be to independently select the required operating mode of the tool.
Rating of the best models
To get acquainted with LVLP spray guns in more detail, it is worth considering the top, where models from different companies are presented.
Stels AG 950
Simple and convenient model for decorative coating. Polished chrome plated metal housing for a long service life.
The air consumption is 110 l / min, the nozzle diameter is 1.5 mm. The rapid connection will ensure a reliable flow of the substance into the nebulizer . The capacity of the reservoir is 0.6 liters and the air connection is 1 / 4F in. The relatively low working pressure of 2 atmospheres is well suited for handling small parts, which improves the quality of the work performed.
The weight of 1 kg makes it possible to easily carry the equipment on construction sites or in the house. The consumption of dyes is 140-190 ml / min, the complete set includes a universal wrench and a brush for cleaning.
Customer reviews make it clear that this model does its job well, mainly for household use. Among the comments can be noted the presence of burrs, chips and other design flaws, which are solved by removing them.
Auarita L-898-14
A reliable tool of the middle price range, which is distinguished by its ease of use. The capacity of the 600 ml tank allows for long-term use in one go. The available additional settings for the torch and air flow allow the user to more accurately adjust the instrument to their needs, based on the current situation. Small dimensions and weight less than 1 kg allow the employee to use this tool for a long time, which will not cause inconvenience.
The air flow per minute is 169 liters, the connection is threaded type, the maximum spray width can be up to 300mm . The nozzle diameter is 1.4 mm, the air fitting is 1 / 4M in. Working pressure - 2.5 atmospheres, which is a good indicator among this type of spray.
Another advantage is the low fire and explosion hazard of the working process when using dyes. The needle and nozzle are made of stainless steel, which increases their service life.
Patriot LV 162B
A spray gun that has everything you need to work successfully. Together with the low price, this model can be called one of the best for its value. The aluminum alloy from which the body is made is durable and resistant to corrosion . Air flow - 200 l / min, nozzle diameter - 1.5 mm, air connection diameter - 1 / 4F. The weight of 1 kg and the large tank capacity of 1 liter make it possible to work for a long time without any inconvenience. Spraying width - 220 mm, working pressure - 3-4 atmospheres.
The body is equipped with a storage loop and an inlet connection is included. The optimal technical set will be useful when performing various types of household work.
